6-8-2019 MONTE CORONA, VALENCIA - LEOPARD MOTH (Zeuzera pyrina)

Leopard Moths (Great Leopard Moth) are large, nocturnal moths famous for their striking black & white spotted wings, resembling a snow leopard. Known for their fuzzy "woolly bear" caterpillars with red bands, they spend most of their lives underground or in trees, feeding on many plants before emerging as adults, which have short lifespans and don't eat, relying on fat reserves for mating and egg-laying. They're found across North America and use foul-smelling fluids and bright colors to deter predators. 

Adult Moth Facts

Appearance: White, translucent wings with blue-black spots; fluffy white body; dark blue/orange abdomen with black spots on the underside.

Size: Large, with a wingspan of 2.25 to 3.5 inches (5.7-8.9 cm).

Behavior: Nocturnal, attracted to lights; live only 6-10 days to mate.

Defense: Release a foul-tasting yellow fluid when threatened. 

Caterpillar Facts (Giant Woolly Bear)

Appearance: Fuzzy black with bright red bands between segments, revealing when curled.

Size: Up to 3 inches long.

Diet: Eat many plants, including sunflowers, willows, cherries, and hostas.

Overwintering: Spend winters as larvae, often under bark or in leaf litter.

Defense: Curl into a ball, showing red bands to deter predators; bristles don't usually irritate skin. 

Life Cycle & Habitat

Habitat: Woodlands, fields, orchards, gardens across Eastern North America.

Duration: Takes 2-3 years to develop, spending most of that time as a 

caterpillar.

23-5-2019 MANA POOLS, ZIMBABWE - CAPE WILD DOG (Lycaon pictus ssp. pictus) PHOTO COURTESY OF MRS VALERIE FISHER

The African wild dog (Lycaon pictus), also called painted dog and Cape hunting dog, is a wild canine native to sub-Saharan Africa. It is the largest wild canine in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by dentition highly specialised for a hypercarnivorous diet and by a lack of dewclaws.

It is estimated that there are around 6,600 adults (including 1,400 mature individuals) living in 39 subpopulations, all threatened by habitat fragmentation, human persecution and outbreaks of disease. As the largest subpopulation probably consists of fewer than 250 individuals, the African wild dog has been listed as endangered on the IUCN Red List since 1990.

The African wild dog is a specialized hunter of terrestrial ungulates, mostly hunting at dawn and dusk, but also displays diurnal activity. It captures its prey by using stamina and cooperative hunting to exhaust them. Its natural competitors are lions and spotted hyenas: the former will kill the dogs where possible whilst the latter are frequent kleptoparasites. Like other canids, the African wild dog regurgitates food for its young but also extends this action to adults as a central part of the pack's social unit. The young have the privilege of feeding first on carcasses.

The African wild dog has been revered in several hunter-gatherer societies, particularly those of the San people and Prehistoric Egypt.

18-5-2019 BUMI HILLS, ZIMBABWE - LITTLE BEE-EATER (Merops pasillas)

The Little Bee-eater, scientifically known as Merops pusillus, is a diminutive and vibrant member of the bee-eater family, Meropidae. This species is adorned with green upper parts and a yellow throat, complemented by a striking black gorget. The upper breast is a rich brown, which gently transitions to a buffish ochre on the belly. Their wings exhibit a blend of green and brown hues, while their beaks and legs are a stark black. Measuring a mere 15–17 cm in length, they hold the title of the smallest African bee-eater. Both males and females are similar in appearance.

When identifying the Little Bee-eater, look for its bright green upper parts, yellow throat, and the distinctive black gorget. The rich brown of the upper breast and the buffish ochre belly are also key characteristics. Their small size and black beak and legs can help distinguish them from other bee-eaters.

These birds favor open country with an abundance of bushes, showing a preference for areas near water sources.

The Little Bee-eater is a resident of Sub-Saharan Africa. Their movements are seasonal, often dictated by the patterns of rainfall rather than long-distance migration.

Little Bee-eaters are known for their abundance and tame nature within their range. They are often seen perched low, sometimes just a meter above the ground. They roost communally, aligning themselves neatly on a tree branch.

Typically a quiet species, the Little Bee-eater's call is a soft "seep," which can be heard intermittently.

Solitary nesters by nature, Little Bee-eaters excavate tunnels in sandy banks for their nests, occasionally utilizing the entrance of an Aardvark den. They lay a clutch of 4 to 6 spherical white eggs, with both parents sharing the responsibility of egg care.

True to their name, Little Bee-eaters primarily consume insects, with a particular fondness for bees, wasps, and hornets. They exhibit remarkable agility, capturing their prey mid-air from an open perch and then removing the stinger by striking the insect against a hard surface before consumption.

The Little Bee-eater is currently classified as Least Concern on the IUCN Red List, with an estimated population of 60 to 80 million individuals.

18-5-2019 BUMI HILLS, ZIMBABWE - COMMON IMPALA (MALE) (Aepyceros melampus ssp. melampus) PHOTO COURTESY OF MRS VALERIE FISHER

The impala (Aepyceros melampus) is a medium-sized antelope that is found in Africa. It was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. The impala is known for two characteristic leaps that constitute an anti-predator strategy.

Impala is an elegant and magnificent species of antelope. The animal has slender body with the identifying "M"-like marking on the rear. This medium-sized antelope possesses thin, pointed horns with tips, lying far apart from each other. Males of this species are identified by the characteristic "S"-like horns. The elegant limbs of these animals have scent glands behind the ankles. The overall coloration of their fur is red-brown with paler sides. In addition, they have black and white colored areas on their body. Thus, the tail, belly, chin, lips, inside ears as well as the lines above the eyes are colored with white. Meanwhile, black bands cover their thighs, tail, forehead and ear tips.

5-8-2019 MONTE CORONA, VALENCIA - STRIPED GRAYLING BUTTERFLY (Hipparchia fidia)

Hipparchia fidia, the striped grayling, is a butterfly of the family Nymphalidae. It is found on the Iberian Peninsula, the Balearic Islands and in south-eastern France and the bordering parts of Italy and North Africa.

S. fidia L.  Above similar to the preceding [ fatua ], but the underside much more variegated and brighter: the ocelli of the forewing large, broadly bordered with yellow, there being before them white smears which are proximally bordered by a black line. On the underside of the hindwing the exterior black discal line projects behind the apex of the cell as a broad tooth; it is externally broadly white and beyond it there are moreover strong white smears extending towards the distal margin.

The wingspan is 48–56 millimetres (1.9–2.2 in).

The butterflies fly from July to August depending on the location.

The larvae feed on various types of grass.

5-8-2019 VILLALONGA RESERVOIR, VALENCIA - FURROW SPIDER (Genus Larinioides)

Larinioides is a genus of orb-weaver spiders commonly known as flying spiders and first described by Lodovico di Caporiacco in 1934. They mostly occur in temperate climates around the northern hemisphere. The name is derived from the related araneid spider genus Larinia, with the meaning "like Larinia".

As of April 2019 it contains seven species:

Larinioides chabarovi (Bakhvalov, 1981) – Russia (Central Siberia to Far East)

Larinioides cornutus (Clerck, 1757) – North America, Europe, Turkey, Israel, Caucasus, Russia (Europe to Far East), Iran, China, Korea, Japan

Larinioides ixobolus (Thorell, 1873) – Western Europe to Central Asia

Larinioides jalimovi (Bakhvalov, 1981) – Russia (Far East), Korea

Larinioides patagiatus (Clerck, 1757) – North America, Europe, Turkey, Caucasus, Russia (Europe to Far East), Central Asia, China, Mongolia, Japan

Larinioides sclopetarius (Clerck, 1757) – Europe, Caucasus, Russia (Europe to Central Asia), China, Korea. Introduced to North America

Larinioides suspicax (O. Pickard-Cambridge, 1876) – Europe, North Africa to Central Asia

5-6-2019 KHWAI CAMP, BOTSWANA - BENNETT'S WOODPECKER (Campethera bennettii)

Bennett's woodpecker (Campethera bennettii) is a species of bird in the family Picidae. It is found in woodlands and bushes in Africa. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.

This species was described by Andrew Smith in 1836. Two subspecies are recognised: Campethera bennettii bennettii and C. b. capricorni. The common name and Latin binomial commemorate the British naturalist Edward Turner Bennett. Bennett's woodpecker, the fine-spotted woodpecker, the Nubian woodpecker and the speckle-throated woodpecker form a superspecies.

Bennett's woodpecker is about 24 cm (9.4 in) long and weighs 61–84 g (2.2–3.0 oz). The male's forehead, crown and nape are red. The chin and throat are white. The upperparts are brown, yellow and white. The underparts are pale yellow, and there are dark spots on the breast and flanks. The eyes are red, the beak is grey, and the legs are bluish-green or grey-green. The female has a black forehead with white spots, and its ear coverts and throat are brown or blackish-brown. The juvenile bird has a black forehead and crown and darker upperparts. The subspecies capricorni is slightly larger, and its underparts have a deeper colour and fewer spots.

This woodpecker is found in Angola, Botswana, Burundi, Democratic Republic of the Congo, Eswatini, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Zambia, and Zimbabwe, and it has a patchy distribution. Its habitat is woodlands and bushes, including miombo, Baikiaea, Acacia and mopane woodlands.

Bennett's woodpecker is found singly, in pairs or in family groups. It mostly forages on the ground, either bare or with short grass, and also feeds in trees. It mostly eats ants and termites, including their eggs. Its calls include chuur notes, a series of wi-wi-wi-wi, kee-kee-kee or ddrahh, ddrahh, ddray-ay, ddray-ay, and a chattering wirrit-wirrit. Breeding occurs from August to February. The woodpecker excavates or reuses holes in trees. Three eggs are laid and then incubated for 15 to 18 days.

The species has a stable population and there is no evidence of substantial threats, so the IUCN has assessed it as a least-concern species.

31-5-2019 THORNTREE CAMP, ZAMBIA - WHITE FRONTED BEE-EATER (Merops bullockoides)

The White-fronted Bee-eater, known scientifically as Merops bullockoides, is a vibrant and slender bird adorned with a striking black mask and a white forehead. Its square tail and bright red throat patch are distinctive features. Measuring at 23 cm in length, the bird's upperparts are a lush green, while its underparts boast a warm cinnamon hue. Its call is a resonant, deep squeak that carries through the air.

A bright and colorful bee-eater; the red throat and white line under the black face mask render it unmistakable. Pairs and groups inhabit woodland adjacent to watercourses, hillsides, and scrub, especially near earthen banks, where nesting colonies are formed by up to 450 individuals burrowing into the dirt. They have one of the most complex of all avian societies, featuring families, clans, and pirates! A nasal rolling “ngyaaau” is the main vocalization.

To identify the White-fronted Bee-eater, look for its unique combination of colors: a black mask, white forehead, green upperparts, and cinnamon underparts. The square tail and bright red throat patch are also key identifiers. Listen for its deep squeaking call as a helpful auditory clue.

This species thrives in the open savannahs of sub-equatorial Africa, often found near gullies where their insect prey, particularly bees, are abundant.

The White-fronted Bee-eater is widely distributed across the savannah regions of sub-equatorial Africa, where it is a common sight in its preferred habitat.

The White-fronted Bee-eater exhibits a complex social structure, nesting in colonies that can average around 200 individuals. These colonies are not just for breeding but also serve as a communal space for roosting and socializing. The birds demonstrate cooperative breeding, with non-breeding individuals acting as helpers to their kin, significantly increasing the success rate of raising young.

The diet of the White-fronted Bee-eater primarily consists of bees, but it also includes other flying insects, depending on seasonal availability. They employ two hunting strategies: making swift hawking flights from lower branches or gliding down from perches to hover momentarily before snatching their prey mid-flight.

The White-fronted Bee-eater is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline or habitat loss at a global scale.

31-5-2019 THORNTREE CAMP, ZAMBIA - TAWNY FLANKED PRINIA (Prinia subflava)

The tawny-flanked prinia (Prinia subflava) is a small passerine bird belonging to the genus Prinia in the family Cisticolidae, a family of Old World warblers. It is widespread and common in most parts of Africa south of the Sahara. The plain prinia (P. inornata) of southern Asia was formerly included in this species but is now usually considered to be a separate species.

The tawny-flanked prinia is 11–12 cm (4.3–4.7 in) in length with a long, narrow, graduated tail[6] and a fairly long, slender bill. The tail is often held erect or waved from side to side. The upperparts are grey-brown with rufous-brown edges to the flight feathers and a rufous tinge to the rump. The throat and breast are whitish while the flanks and vent are warm buff. There is a whitish stripe over the eye and the lores are dark. The tail feathers have a white tip and a dark subterminal band.

The sexes are similar in appearance. Non-breeding birds have a longer tail than breeding birds. Juveniles have pale yellow underparts and a yellowish bill. There are many recognised subspecies.

The call is short, wheezy and rapidly repeated. The song is a monotonous series of shrill notes. The male often sings from an exposed perch.

The pale prinia (P. somalica) of North-east Africa is similar but paler and greyer with whitish flanks. It inhabits drier, more open habitats than the tawny-flanked prinia. The river prinia (P. fluviatilis) of West Africa is also paler and greyer and has a longer tail. It is restricted to waterside vegetation.

There are ten subspecies distributed across most parts of sub-Saharan Africa except for the driest and wettest areas. It is absent from much of the Congo Basin, southern Namibia, south-west Botswana and the western half of South Africa. It is found amongst shrubs and grass in a variety of habitats including woodland, savanna and cultivated areas. It adapts well to man-made habitats and is not considered to be threatened.

It feeds on insects and other invertebrates. It forages in small flocks which move through shrubs and undergrowth.

The nest is purse-shaped and made of strips of grass woven together. It is built one to two metres above the ground. Two to four eggs are laid; they are variable in ground colour and usually have brown or purple spots or blotches.

4-8-2019 VILLALONGA RESERVOIR, VALENCIA - CROSS ORBWEAVER SPIDER (Araneus diadematus)

The spider species Araneus diadematus is commonly called the European garden spider, cross orbweaver, diadem spider, orangie, cross spider, and crowned orb weaver. It is sometimes called the pumpkin spider, although this name is also used for a different species, Araneus marmoreus. It is an orb-weaver spider found in Europe, where it is native, and North America, where it was introduced.

A. diadematus has a holarctic distribution throughout Europe and across North America, from southern Canada to Mexico, and from British Columbia to Newfoundland.

Individual spiders' colourings can range from extremely light yellow to very dark grey, but all A. diadematus spiders have mottled white markings across the dorsal abdomen, with four or more segments forming a cross. The markings are formed in cells filled with guanine, which is a byproduct of protein metabolism.

Adult females range in length from 6.5 to 20 mm (0.26 to 0.79 in), while males range from 5.5 to 13 mm (0.22 to 0.51 in). Occasionally, the female will eat the male directly after mating. 

31-5-2019 THORNTREE CAMP, ZAMBIA - BROWN HOODED KINGFISHER (Halcyon albiventris)

The brown-hooded kingfisher (Halcyon albiventris) is a species of bird in the subfamily Halcyoninae, the tree kingfishers. It has a brown head and blackish and turquoise wings. It is found in Sub-Saharan Africa, living in woodland, scrubland, forest edges, and also suburban areas. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.

This species was described as Alcedo albiventris by Giovanni Antonio Scopoli in 1786. Four subspecies are recognised: Halcyon albiventris albiventris, H. a. orientalis, H. a. prentissgrayi and H. a. vociferans. Subspecies hylophila and erlangeri have also been described, but they are not considered distinct enough.

The brown-hooded kingfisher is about 22 cm (8.7 in) long. The head is brown, with blackish streaks. There is a broad buffy collar above the brownish-black mantle. The wing coverts are mostly brownish-black, and the secondary flight feathers are turquoise. The rump is azure-blue. The chin is white, the breast is tawny with some dark streaks, and the belly is buffy. The beak is red, tipped brown, the legs are carmine, and the eyes are dark brown. The female has dark brown upperparts, and its underparts are more streaked than the male. The juvenile bird is duller, with scalloped whitish underparts. The subspecies differ in shade and streaking.

This kingfisher is found in Sub-Saharan Africa, in Gabon, Congo, the Democratic Republic of the Congo, Angola, Kenya, Tanzania, Zambia, Somalia, Mozambique, Malawi, Zimbabwe, Botswana, Namibia, South Africa and Eswatini. It occurs below 1,800 m (5,900 ft) in elevation, living in woodland, grassland with trees, scrubland, forest edge, and also cultivations, parks and gardens. It sometimes occurs near water, and can adapt to suburban habitats. Most populations do not migrate, but there is evidence of seasonal movements in some areas.

This kingfisher is generally seen alone or in pairs. It usually forages on the ground, mainly feeding on insects, and also eating scorpions, reptiles, small birds, rodents and fishes. Eating snakes and lizards as long as 25 cm (9.8 in) has been reported. The song, given while vibrating the wings, is a tiiiu or ki-ti-ti-ti trill, and a sharp cheerit is given when alarmed. The breeding season is mainly between September and April. A burrow nest is dug in a river bank, gully or road cutting. The family stays together for a few weeks after breeding.

The Brown-hooded Kingfisher's vocal repertoire includes a song that sounds like a "tiiiu" or a "ki-ti-ti-ti" trill, often accompanied by wing vibrations. When alarmed, it emits a sharp "cheerit."

Breeding occurs mainly between September and April. The kingfisher digs a burrow nest in a river bank, gully, or road cutting, where it raises its young. After the breeding season, the family stays together for a few weeks.

The Brown-hooded Kingfisher feeds on a variety of prey, including insects, scorpions, reptiles, small birds, rodents, and fish. It is an adept hunter, capable of taking on prey such as snakes and lizards up to 25 cm long.

The IUCN has classified the Brown-hooded Kingfisher as a species of Least Concern, thanks to its large range, stable population, and lack of significant threats.

31-5-2019 THORNTREE CAMP, ZAMBIA - BLACK COLLARED BARBET ( Lybius corquatus)

The black-collared barbet (Lybius torquatus) is a species of bird in the family Lybiidae which is native to sub-Saharan Africa. Indigenous names include Rooikophoutkapper in Afrikaans, isiKhulukhulu and isiQonQotho in Zulu, and Isinagogo in Xhosa.

It is found in Sub-Saharan Africa through Angola, Botswana, Burundi, Democratic Republic of the Congo, Eswatini, Kenya, Lesotho, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe.

The black-collared barbet usually is about 20–25 cm long, plump-looking and has a large head. It also has the heavy bill fringed with bristles that is characteristic of the genus Lybius. This barbet has a very obvious black collar and head which gives reference to its name. It also has a fire-engine red coloring around the eyes and beak. It has morphologically variable coloring because there is a replacement of a red head with a black head. It also has a more intense color and is larger than other barbets. This bird is also sexually monomorphic, which means that there is generally no phenotypic difference between the males and females of this species. The morphology, size and behavior are basically the same.

The black-collared barbet is one of the many duetting species in the genus Lybius and it regularly uses duetting in its day-to-day life. There are no solitary song instances heard from this species. Also, the repertoire of the duets do not vary greatly. This species is readily recognized by its loud duet, commonly rendered as "too-puddly too-puddly too-puddly" or "too-doodle too-doodle".... accompanied by wing-flicking. In addition to the wing-flicking, the birds in the pair face each other while calling and lean forward while bowing ceremoniously to each other. This bird produces a variety of calls including its snarling warning call and loud buzzing. The snarling could be the initiating sound of the duet.

The "too-puddly" song is actually an antiphonal duet. That means that one bird out of the pair sings the first note, then the other bird in the pair sings the second note. To bystanders, this does not sound like it comes from two different birds. It has distinct sexual duet roles after a greeting ceremony and the partner's notes do differ. The birds do not sing simultaneously, but are synchronized in their duets. The time between when one bird stops singing to when the other bird in the pair picks the song up is called the auditory response time for the duet. The approximate auditory response time for this bird is 178 ms.

This species also incorporates more wing and flight displays into their greeting ceremonies, mating, and territorial displays. It is a gregarious species, often acting in concert when driving off intruders and roosting together (up to 15 recorded) in nest holes. Their flight is direct with a loud whirring of wings.

31-5-2019 THORNTREE CAMP, ZAMBIA - ARROW MARKED BABBLER (Turdoides jardineii ssp. tamalakanei)

The arrow-marked babbler is a medium-sized babbler, 22 to 25 cm (8.7–9.8 in) in length and weighing 56 to 85 g (2.0–3.0 oz). The common name for the species is derived from its plumage, which is brownish-grey above and lighter below, with white tips to the feathers on the throat, neck and head. The outer iris is bright red and the inner bright yellow or orange. Males and females are identical in appearance. Juveniles have brown eyes and less arrow-shaped streaking on the breast.

The arrow-marked babbler lives in social groups of between 3 and 15 birds (six being the average) that defend large territories, with the size of the territory being dependent upon the number of individuals in the group. They feed on insects, spiders and sometimes snails and lizards, as well as fruits. Foraging occurs near the ground, sometimes in association with other babblers or bulbuls.

This angry-looking bird lives, breeds and travels in groups of between 4 and 12 or so: very noisy, very active, aggressively flicking aside leaves etc. to find insects and sometimes small reptiles. It also eats seeds and small fruit.  They are hard to miss and common in Harare suburbs, very frequent visitors in the early mornings and evenings. 

They are monogamous, meaning that they mate in single pairs, but co-operative, meaning that the group works together to raise the chicks.  As they move together as a group, they are constantly calling to each other, presumably to keep the group together.  Their alarm call is very characteristic: starting with an individual bird, it swells and grows louder and louder to a deafening crescendo.

31-5-2019 THORNTREE CAMP, ZAMBIA - WAHLBERG STRIPED SKINK (Trachylepis striata ssp. wahlbergi)

Trachylepis wahlbergii, also known commonly as Wahlberg's striped skink, is a species of lizard in the family Scincidae. The species is native to Southern Africa.

Trachylepis wahlbergii has been considered a subspecies of Trachylepis striata. Whether T. wahlbergii is truly distinct from T. striata is not fully settled.

T. wahlbergii occurs in southern Angola, northern Botswana, northern Namibia, western Mozambique, Zambia, and northern, western and southern Zimbabwe.

The specific name, wahlbergi, is in honour of Swedish Naturalist Johan August Wahlberg.

T. wahlbergii is viviparous. In animals, viviparity is the development of the embryo inside the body of the mother, with the maternal circulation providing for the metabolic needs of the embryo's development, until the mother gives birth to a fully or partially developed juvenile that is at least metabolically independent.

31-5-2019 THORNTREE CAMP, ZAMBIA - AFRICAN PIED WAGTAIL (Motacilla aguime)

The African Pied Wagtail (Motacilla aguimp) is a distinctive black-and-white bird of sub-Saharan Africa, known for its energetic tail-wagging as it hunts insects on the ground near water or in towns, utilizing diverse nesting spots from reedbeds to human structures, and often feeding on insects, seeds, and even scraps, with both parents raising young in monogamous pairs. 

Appearance & Identification

Colors: Striking black, white, and grey-black plumage with a bold white eyebrow and wing panels.

Size: Around 18 cm long with a distinctive long tail that bobs constantly. 

Habitat & Diet

Habitat: Found near water (rivers, marshes) but thrives in human-altered areas like towns, gardens, and farms across tropical Africa.

Diet: Primarily insectivorous (flies, ants, grasshoppers, etc.) but also eats seeds, tadpoles, small fish, and human food scraps. 

30-7-2019 BOTANICO ATLANTICO GIJON, ASTURIAS - SPANISH GATEKEEPER BUTTERFLY (Pyronia bathseba)

Pyronia bathseba, the Spanish gatekeeper, is a butterfly of the family Nymphalidae. It is found on the Iberian Peninsula and in France, Morocco, and Algeria. A similar gatekeeper species is Pyronia tithonus, which is found in northern Europe.

The wingspan is 18–19 mm. The butterfly is on wing from May to July depending on the location.

The larvae feed on Poaceae species, mainly Brachypodium species.

30-7-2019 BOTANICO ATLANTICO GIJON, ASTURIAS - BEAUTIFUL DEMOISELLE DAMSELFLY (FEMALE) (Calopteryx virgo)

The beautiful demoiselle (Calopteryx virgo) is a species of damselfly belonging to the family Calopterygidae. It is found in Europe, North Africa, and Western Asia. It is often found along fast-flowing waters.

Females can lay up to 300 eggs at a time on floating plants, such as water-crowfoot. Like the banded demoiselle, they often submerge underwater to do so, and the eggs hatch around 14 days later. The larvae are stick-shaped and have long legs. They develop over a period of two years in submerged vegetation, plant debris, or roots. They usually overwinter in mud or slime.

The larvae of the beautiful demoiselle develop over 10 to 12 stages, each of which ends with a moult. The body length varies and depends on environmental conditions. In the final stage (F-0-stage), larvae are 3.5–4.6 millimetres long and weigh about 4 milligrams, slightly smaller than those of the banded demoiselle. The larvae of the beautiful demoiselle can be recognized by the bristles of the gills on their abdomen.

The body of the larvae shows only a relatively small adjustment to the fast-flowing waters of their habitat. The body is not flattened, but it is very slim, and the legs are long and end with strong claws. Because they reside within the water, and mainly in quiet areas, the danger of being swept by the flow is relatively low. If this happens, they stretch out to grab onto passing vegetation or substrate.

30-7-2019 BOTANICO ATLANTICO GIJON, ASTURIAS - GUADARRAMA WALL LIZARD (Podarcis guadarramae)

The Guadarrama wall lizard (Podarcis guadarramae) is a medium-sized lizard endemic to the granite rocks of the Sierra de Guadarrama and other ranges in western-central Iberia. It is characterized by a flattened head, slender body, and coloration ranging from brown to bright green with dark spots. This species is insectivorous, laying 3-11 eggs and hibernating in winter to escape cold temperatures. 

Description and characteristics

Appearance: Males often have bright, contrasting pale dorsolateral stripes, while females may have uninterrupted or fragmented pale stripes.

Head: A key distinguishing feature is its flattened head with an elongated snout.

Size: Adult males have an average snout-vent length of about 53.8 mm, with females averaging 51.6 mm.

Coloration: Color can range from brown to bright green with dark spots, and it may have a high proportion of black elements in its coloration. 

Habitat and behavior

Habitat: It is a rupicolous species, meaning it lives among rocks and scree, particularly on granite substrates in its namesake range. It can also be found in other rocky areas, including artificial stone walls, and sometimes in sandy areas within forests.

Diet: It is primarily insectivorous, consuming a wide variety of terrestrial invertebrates, but it may also eat fruit and berries.

Reproduction: It is an egg-laying species, typically laying 3-11 eggs once or twice per year, depending on the length of the summer.

Behavior: The Guadarrama wall lizard hibernates for several months to avoid winter cold. Some populations at higher altitudes have larger body size and lay more eggs, which is likely related to environmental factors like food and water availability. 

Geographic distribution

Range: The species is found in the mountain ranges of the Sistema Central in Spain, from the Sierra del Alto Rey in the east to the Sierra de Guadarrama and Sierra de Gredos in the west.

Endemic to: It is endemic to this region, making its presence particularly important to the ecosystem of the Sierra de Guadarrama National Park. 

26-7-2019 AVILA, CASTILLE AND LEON - EURASIAN JACKDAW (Coloeus monedula)

The western jackdaw (Coloeus monedula), also known as the Eurasian jackdaw, the European jackdaw, or simply the jackdaw, is a passerine bird in the crow family. Found across Europe, western Asia and western North Africa; it is mostly resident, although northern and eastern populations migrate south in the winter. Four subspecies are recognised, which differ mainly in the colouration of the plumage on the head and nape. Linnaeus first described it formally, giving it the name Corvus monedula. The common name derives from the word jack, denoting "small", and daw, a less common synonym for "jackdaw", and the native English name for the bird.

Measuring 34–39 centimetres (13–15 in) in length, the western jackdaw is a black-plumaged bird with a grey nape and distinctive pale-grey irises. It is gregarious and vocal, living in small groups with a complex social structure in farmland, open woodland, on coastal cliffs, and in urban settings. Like its relatives, jackdaws are intelligent birds, and have been observed using tools. An omnivorous and opportunistic feeder, it eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. Western jackdaws are monogamous and build simple nests of sticks in cavities in trees, cliffs, or buildings. About five pale blue or blue-green eggs with brown speckles are laid and incubated by the female. The young fledge in four to five weeks.

27-7-2019 RIBADESELLA, ASTURIAS - BLACK HEADED GULL (Chroicocephalus ridibundus)

The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of the Palearctic in Europe and Asia, and also locally in smaller numbers in coastal eastern Canada. Most of the population is migratory and winters further south, but many also remain in the milder areas of northwestern Europe. It was formerly sometimes cited as "common black-headed gull" to distinguish it from "great black-headed gull" (an old name for Pallas's gull).

Black-headed gulls were among the birds most heavily hit by the 2023 avian influenza outbreak, with over 4,000 birds killed in Great Britain by early May; similarly high mortality rates were also reported from France, the Netherlands, Italy and Germany.

The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps, and carrion in towns, or invertebrates in ploughed fields with equal facility. It is a noisy species, especially in colonies, with a familiar "kree-ar" call.

It displays a variety of behaviour and adaptations. Some of these include removing eggshells from the nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are found in a variety of different habitats.

27-7-2019 RIBADESELLA, ASTURIAS - SWAN GOOSE (Anser cygnoides var. domesticus)

The Chinese Goose is an international breed of domestic goose, known by this name in Europe and in North America. Unlike the majority of goose breeds, it belongs to the knob geese, which derive from Anser cygnoides and are characterised by a prominent basal knob on the upper side of the bill. It originates in China, where there are more than twenty breeds of knob goose.

Unlike the majority of goose breeds, which derive from the greylag goose, Anser anser, the Chinese belongs to the knob geese, which derive from the swan goose, Anser cygnoides, and are characterised by a prominent basal knob on the upper side of the bill. As the name suggests, it is believed to have originated in China, where there are more than twenty breeds of knob goose.

It was seen in Britain from the early eighteenth century if not before,  and was present in the United States in the latter part of that century – George Washington is believed to have kept some on his plantation at Mount Vernon.

In the twenty-first century it is an endangered breed: it is reported to DAD-IS by seven countries – Australia, Lithuania, Moldova, the Russian Federation, Slovenia, Suriname and the UK – but none of them report population data. Population data was last reported by the United Kingdom in 2002, when there were between 150 and 1000 birds. The Livestock Conservancy in the United States lists it as watch, its third level of concern.

It appears in two varieties: the grey or brown, with colouring similar to that of the wild Anser cygnoides, and the white.  The bill and the knob are black in the grey-brown variety, and orange in the white; the shanks and feet are always orange.  In birds bred for showing the neck is long and slender.

As a layer of eggs it is the most prolific of any breed of goose, usually laying some 50–60 eggs in a season of about five months, but sometimes reaching 100 eggs during that time. The eggs weigh about 120 g, rather less than those of other geese.  Flocks of the geese may be used to guard property or to keep down weeds.

29-7-2019 ISABEL CATOLICA PARQUE GIJON, ASTURIAS - MAINLAND EMU (Dromaius novaehollandiae ssp. novaehollandiae)

The emu (/ˈiːmjuː/; Dromaius novaehollandiae) is a species of flightless bird endemic to Australia, where it is the tallest native bird. It is the only extant member of the genus Dromaius and the third-tallest living bird after its African ratite relatives, the common ostrich and Somali ostrich. The emu's native ranges cover most of the Australian mainland. The Tasmanian, Kangaroo Island and King Island subspecies became extinct after the European settlement of Australia in 1788.

The emu has soft, brown feathers, a long neck, and long legs. It can grow up to 1.9 m (6 ft 3 in) in height. It is a robust bipedal runner that can travel great distances, and when necessary can sprint at 48 km/h (30 mph). It is omnivorous and forages on a variety of plants and insects, and can go for weeks without eating. It drinks infrequently, but takes in copious amounts of fresh water when the opportunity arises.

Breeding takes place in May and June, and fighting among females for a mate is common. Females can mate several times and lay several clutches of eggs in one season. The male does the incubation; during this process he hardly eats or drinks and loses a significant amount of weight. The eggs hatch after around eight weeks, and the young are nurtured by their fathers. They reach full size after around six months, but can remain as a family unit until the next breeding season.

The emu is sufficiently common to be rated as a least-concern species by the International Union for Conservation of Nature. Despite this, some local populations are listed as endangered, with all the insular subspecies going extinct by the 1800s. Threats to their survival include egg predation by other animals (especially invasive species), roadkills and habitat fragmentation.

The emu is an important cultural icon of Australia, appearing on the coat of arms and various coinages. The bird features prominently in Indigenous Australian mythologies.

29-7-2019 ISABEL CATOLICA PARQUE GIJON, ASTURIAS - BARNACLE GOOSE (Branta leucopsis)

The Barnacle Goose, Branta leucopsis, is a medium-sized member of the black geese genus Branta. It is characterized by its striking black and white plumage, with a distinctive white face, black head, neck, and upper breast. The underparts are predominantly white, while the back and wings boast a silver-gray hue adorned with black-and-white bars that glisten in the sunlight. Adults typically measure between 55 to 70 centimeters in length, with a wingspan stretching from 130 to 145 centimeters, and weigh between 1.21 and 2.23 kilograms.

When observing these geese, look for the white face contrasting sharply with the black head and neck. In flight, the V-shaped white rump patch and silver-gray underwing linings are telltale signs of the species. The barred pattern on the back and wings is also a key feature to distinguish the Barnacle Goose from similar species.

Barnacle Geese are known to breed in the high Arctic regions, often selecting precipitous cliff edges to place their nests, well out of reach of terrestrial predators. They favor coastal areas and are commonly found in wetland environments during winter.

The species has a circumpolar distribution, with breeding grounds in Greenland, Svalbard, and the Russian Arctic. Wintering areas include the British Isles, particularly the Hebrides and parts of western Ireland, as well as the Wadden Sea area in Denmark, Germany, and the Netherlands. Notably, new breeding populations have established in Iceland and along the Baltic Sea.

These geese are renowned for their perilous breeding strategy, where goslings must leap from towering cliffs to join their parents on the ground below. This dramatic plunge is a rite of passage, ensuring that only the fittest survive. The goslings imprint on their parents and follow them to feeding grounds, learning to forage under their guidance.

The Barnacle Goose communicates with a repertoire of honking calls, which can be heard during their social interactions and as they fly in formation during migration.

Nesting typically occurs on cliff ledges, where the female lays her eggs far from the reach of predators. The young goslings must make a daring leap to the ground to join their parents after hatching, a testament to the harsh realities of life in the Arctic.

These geese graze on a variety of vegetation, including grasses, aquatic plants, and mosses. They are herbivorous and often feed in wetlands and coastal areas where such food is abundant.
